Masonry Structure Non-Prefabricated Panel

The term 'house diamond structure non-prefabricated panel' may contain an expression error. Based on available information, it is more likely to be 'masonry structure non-prefabricated panel'. Here are its core features and performance:

Structural Form and Materials

The masonry structure non-prefabricated panel uses masonry walls as the main load-bearing and enclosure structure. The wall materials are usually fired bricks, concrete bricks, or stones, which are bonded together with mortar to form an integral structure. The floor slab adopts the in-situ casting process, where a concrete layer is formed by mixing mortar (cement mortar) with stones. During casting, formwork needs to be erected and vibrated densely. Unlike prefabricated panel structures, its floor slab and wall are directly connected through in-situ casting, forming a continuous load-bearing system. However, its overall strength and stability are limited by the compressive performance of the masonry materials and the quality of concrete casting.

Construction Method and Process Characteristics

The construction of this structure is divided into two stages: wall masonry and floor slab casting. Wall masonry should follow the principle of 'horizontal and vertical, full mortar' to ensure the integrity of the masonry. Before floor slab casting, formwork needs to be installed and pipelines need to be embedded. During casting, the concrete mix ratio and vibration time should be controlled to avoid defects such as honeycombs and pockmarks. The combined process of pure masonry and mortar casting, although having a relatively long construction period, allows for flexible adjustment of the floor slab thickness and layout to meet different functional requirements.

Overall Performance Advantages

1. Integrity: The in-situ cast floor slab and wall are connected through steel bars or concrete, forming a spatial stiffness system that effectively resists horizontal loads (such as earthquakes and wind loads) and reduces structural deformation.
2. Sound Insulation and Waterproofing: The in-situ cast concrete floor slab has a high density and can block airborne sound. When combined with waterproofing membranes or coatings, it can form a continuous waterproof layer and reduce the risk of leakage.
3. Seismic Performance: Compared with prefabricated panel structures, the connection between the in-situ cast floor slab and wall is stronger, and it is less likely to have panel detachment or misalignment during earthquakes, meeting the requirements of seismic design codes.

Limitations

Limited by the compressive performance of masonry materials, masonry structure non-prefabricated panels are mostly used in low-rise residential buildings (such as those below 6 floors). If high-rise buildings need to be constructed, additional structural columns, ring beams, and other reinforcement measures are required, or a frame structure should be adopted. In addition, the in-situ casting process has relatively high technical requirements for the construction team. If the concrete curing is insufficient or the formwork is removed too early, it may lead to floor slab cracking and affect durability.
